The Entomostraca that form the subject of the following remarks are from the Carboniferous rocks of Nova Scotia, and were submitted to us for examination, at different times, by Principal Dr. J. W. Dawson, C.M.G., F.R.S., of McGill College, Montreal.

1990 marks the vicesenary of the death of Bertrand Russell, in his 98th year; and this arithmetical property is sufficient reason to review the historical research that has been published on his life and work during the past 20 years. During his long life he had already become the subject of historical research in many of his activities; but this interest accelerated considerably around the time of his death because in the mid 1960s he had decided to sell the bulk of his manuscripts, to raise money to finance his current projects. One of these was the series of conferences financed by the Canadian industrialist Cyrus Eaton, which began at his birthplace of Pugwash, in Nova Scotia. An alumnus of McMaster University at Hamilton, Ontario, Eaton announced that he would put forward a considerable sum of his own money if the papers went to McMaster. Some deft work by the librarian there secured the rest of the required capital, and the papers were purchased in 1968. Thus was created the ‘Bertrand Russell Archives’, as Russell insisted it be called, rejecting the original appellation of ‘Archive’; it is a major resource for British history of Russell’s time, and for the many other concerns in which he was involved. Soon after its launch in 1972, the first Russell conference at McMaster took place, to commemorate the centenary of his birth; its proceedings were published as a book four years later.

The literature dealing with the coleopterous fauna of Nova Scotia is extremely scanty, the old lists of Jones (1869) and Evans (1899) still being the most comprehensive treatments of the subject. Leng (19201, it is true, interested principally in limital records, indicated in his catalogue the presence in Nova Scotia of all species known by him to occur there. But a list compiled from his catalogue is far from complete. Of recent papers, two by Brown (1910, 1950) on introduced European species are the most interesting.

In the past few years, the subject of administrative law remedies has been studied intensively in many common law jurisdictions. In this article, David Mullan examines the various reforms and proposals for reform and concludes that none is completely satisfactory and indeed that some compound previous problems and create new ones as well Nevertheless, he sees some merit in the New South Wales and Nova Scotia solutions which emerged as part of a general reform of the civil procedure rules and not as a separate statutory enactment.

Social assistance and related programs are an important part of life in the 13 Mi’kmaq communities of Nova Scotia. Given the substantive importance of social assistance and related programs in Mi’kmaq communities, it is surprising how little research has been conducted on the subject. This research aims to understand the origins of economic dependence and the related emergence of social assistance among the Mi’kmaq in Nova Scotia. We identify key historical periods and processes that have shaped the current policy landscape. A defining characteristic of social policy on reserve has been the fact that First Nations themselves have had very little say in how programs such as social assistance are designed and delivered. There is hope that a more self-determined and holistic approach may emerge.

The occurrence of remains of land animals in the interior of erect fossil trees is, so far as yet known, confined to certain horizons in the coal-field of the South Joggins in Nova Scotia. These remains were first discovered by Sir Charles Lyell and the writer in the summer of 1851. They were found in fragments of the sandstone filling an erect Sigillaria which had fallen from the cliff near Coal Mine Point. As other erect trees occurred in the beds from which this was supposed to have fallen, search was made by the writer in subsequent visits for additional trees; but up to 1876 only three of those which became accessible by the wasting of the beds were found to yield animal fossils. These, however, afforded many additional specimens, and several new species of Batrachians and Millipedes. The results of these explorations were published at various times in the Journal of the Geological Society of London, in a work entitled ‘Air-breathers of the Coal Period,' and in 'Acadian Geology;' and Dr. Scudder described the new species of Millipedes in the Memoirs of the Boston Society of Natural History. The beds containing the productive trees being thus well known, and being exposed in a cliff and in a reef extending into the sea, it seemed probable that many others might be obtained by quarrying operations of no great difficulty. In 1878 the subject was brought under the notice of the Council of the Royal Society, and a grant of £50 was made from the Government Fund to aid in the extraction of these trees and the collection of their contents. With the aid of this grant, a thorough survey and examination has been made of the cliff and reef by Mr, Albert T. Hill, C. E., by Mr. W. B. Dawson, C. E., and by myself, with the kind aid of B, B. Barnhill, Esq., Superintendent of the Joggins Coal Mines. By these means, along with the removal of fallen débris and sand from the outcrop of the beds, twenty additional trees were discovered and were extracted by cutting and blasting; affording many additional specimens and much information respecting the conditions of accumulation of the beds and the manner of entombment of the animal remains.

THE germ of that which follows came into being many years ago in the days of my youth as a university instructor and assistant professor. It was generated by the then quite outspoken attitude of colleagues in the “exact sciences”; the sciences of which the subject-matter can be exactly weighed and measured and the force of its movements mathematically demonstrated. They assured us that the study of languages and literature had little or nothing scientific about it because: “It had no domain of concrete fact in which to work.” Ergo, the scientific spirit was theirs by a stroke of “efficacious grace” as it were. Ours was at best only a kind of “sufficient grace,” pleasant and even necessary to have, but which could, by no means ensure a reception among the elected.

In this paper an orbit computation program for artificial satellites is presented. This program is operational and it has already been used to compute the orbits of several satellites.After an introductory discussion on the subject of artificial satellite orbit computations, the features of this program are thoroughly explained. In order to achieve the representation of the orbital elements over short intervals of time a drag-free perturbation theory coupled with a differential correction procedure is used, while the long range behavior is obtained empirically. The empirical treatment of the non-gravitational effects upon the satellite motion seems to be very satisfactory. Numerical analysis procedures supporting this treatment and experience gained in using our program are also objects of discussion.

Rule: I'd like at this point to bring up the subject of cables and wireways around the telescope. We've touched upon this twice during previous sessions: the cable wrap up problem, the communications problem, and data multiplexing problem. I think we'll ask Bill Baustian if he will give us a brief run down on what the electrical run problems are, besides doubling the system every year.

The Mesozoic-Cenozoic coral Order Scleractinia has been suggested to have originated or evolved (1) by direct descent from the Paleozoic Order Rugosa or (2) by the development of a skeleton in members of one of the anemone groups that probably have existed throughout Phanerozoic time. In spite of much work on the subject, advocates of the direct descent hypothesis have failed to find convincing evidence of this relationship. Critical points are:(1) Rugosan septal insertion is serial; Scleractinian insertion is cyclic; no intermediate stages have been demonstrated. Apparent intermediates are Scleractinia having bilateral cyclic insertion or teratological Rugosa.(2) There is convincing evidence that the skeletons of many Rugosa were calcitic and none are known to be or to have been aragonitic. In contrast, the skeletons of all living Scleractinia are aragonitic and there is evidence that fossil Scleractinia were aragonitic also. The mineralogic difference is almost certainly due to intrinsic biologic factors.(3) No early Triassic corals of either group are known. This fact is not compelling (by itself) but is important in connection with points 1 and 2, because, given direct descent, both changes took place during this only stage in the history of the two groups in which there are no known corals.

The growth of Ag films deposited on various substrate materials such as MoS2, mica, graphite, and MgO has been investigated extensively using the in situ electron microscopy technique. The three stages of film growth, namely, the nucleation, growth of islands followed by liquid-like coalescence have been observed in both the vacuum vapor deposited and ion beam sputtered thin films. The mechanisms of nucleation and growth of silver films formed by ion beam sputtering on the (111) plane of silicon comprise the subject of this paper. A novel mode of epitaxial growth is observed to that seen previously.The experimental arrangement for the present study is the same as previous experiments, and the preparation procedure for obtaining thin silicon substrate is presented in a separate paper.
